Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case that stores thin, regular shaped articles in an orderly manner, and is particularly suitable for storing CDs, DVDs, mini disks, credit cards and the like.

[0002]

2. Description of the Related Art As a portable case for accommodating a recording disk, it is common to stack an envelope-shaped bag made of non-woven fabric or the like on a spread case and sew it up at a very low cost. Further, Japanese Patent Laid-Open Nos. 7-137780, 2000-0627756, 2000-149484, etc. are disclosed as those using a bellows shape. They are,
With a structure in which the disc is clamped by the valley-side recess on the side wall of the bellows,
The data surface of the disc is not easily scratched, and the gap between the multiple disc surfaces or between the cover surface and the disc surface naturally expands due to the elasticity of the bellows side wall, so it is easy to take out, has good visibility, and has a high cushioning property. Is characterized.

[0003]

In the case of a general envelope-shaped file, it is necessary to open a gap between two sheets of paper or a film that are in close contact with each other to insert a disc, and it is difficult to take them in and out quickly. Further, when the desired discs are taken out from the overlapping files, it is necessary to search the files one by one. Further, when the disc is taken in and out, the disc rubs against the file material, which may damage the written data.

In the conventional storage device using the bellows shape, since the side surface of the storage space is formed by the pleats which are independently pleated, a gap is created between the side surface and the bottom surface, and dust is introduced. There was a high possibility that Further, in the disclosed storage device using the bellows body, since the bellows used are only folded back like a folding screen, when the folding back of the bellows is increased to accommodate a plurality of discs, the space between the bellows side walls is flexible. It becomes something.
Therefore, in order to make the width of the storage slot constant, an auxiliary structure for restricting the interval of the bellows side wall is added, or a structure for limiting the opening angle to limit the expansion amount of the bellows to a very small amount. Was needed.

[Means for Solving the Problem] Side wall 3 forming a storage chamber
The bottom surface 4 and the bottom surface 4 are integrally formed by a bellows body, and the bellows side wall 3 and the bellows bottom surface 4 are configured as storage slots that are adjacently separated by a bellows mountain fold portion 5. Further, the bellows body has a substantially rectangular shape with respect to the longitudinal direction of the sheet material 6.
Forming transverse folding lines A and B that are provided at equal intervals at right angles, and a vertical folding line C that bends in an obtuse zigzag at intersections D1 and D2 with the transverse folding line in a direction substantially perpendicular to the transverse folding line is in the longitudinal direction of the sheet material. The zigzag polygonal line F, which is formed in two rows symmetrically with respect to the parallel centerline E and shares the outer bending point D2 of the zigzag polygonal line C as an outer bending point, is located inside the zigzag polygonal line C with respect to the center line E. Two rows may be formed at symmetrical positions.

Further, a spread case 1 capable of opening and closing the bellows body.
Alternatively, both end surfaces of the bellows body and the inner surface of the case may be connected so that the bellows body, which is the storage portion, is stretched by storing the split bellows in the split case 2 and opening the case. Further, the bellows body is housed in the spread case 1 or the split case 2 which can be opened and closed, and the protrusion 11 or the case side wall surface 18 is provided on one or both of the inner surfaces of the case which face each other in the closed state of the case. The projection 11 or the side wall surface 18 of the case serves as an abutting surface in the closed state, and the inner surfaces of the both surfaces of the case are substantially parallel to each other.
Alternatively, the case side wall surface 18 may have a shape that covers the bellows opening side surface 7.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a storage device according to the present invention will be described with reference to the drawings. Figure 1 is a spread case 1
It is an example in which a bellows body is attached to the case, and shows a state in which the case is opened. The storage space exposed by opening the case is
The concave and convex portions of the bellows side wall 3 and the bottom surface 4 form a storage slot that is regularly divided. In the storage device of the present invention, by forming the sheet material into a bellows body in a predetermined folding manner, it is possible to give the bellows body itself a property of always keeping the side walls 3 and the bottom surface 4 at a fixed angle. As in this example, it is generally desirable that the angle be substantially right angle.

FIG. 2 shows a state in which the spread case 1 of FIG. 1 is further opened. According to the present invention, since the bellows side wall 3 and the bellows bottom surface 4 are integrally formed, the width of the slot, which is the interval between the bellows side wall 3, does not change regardless of the open / close state of the case as described above. There is no need for a mechanism for regulating the opening angle or a mechanism for limiting the opening angle of the spread case 1. Further, as the spread case 1 is widened, naturally, the interval between the valleys forming each slot is increased, the visibility of the label of the stored disc 19 is improved, and the disc 19 is easily taken in and out. Since the bellows body is difficult to be stretched beyond a certain length, it is possible to appropriately limit the angle when the spread case 1 is fully opened by appropriately selecting the number of folded back bellows.

The shape of the concavo-convex formed on the bellows bottom surface 4 of the storage device of the present invention matches the concavo-convex state of the bellows side wall 3. That is, the bellows bottom surface 4 connected to the mountain fold portion on the bellows side wall 3 is also a mountain fold portion, and similarly, the valley fold portions are also connected to each other. Therefore, each of the slots separated by the bellows mountain fold portion 5 is surely separated from the adjacent slots on the three sides of the side walls and the bottom surface. When the disc 19 is stored in the storage device by mistake, if the disc 19 is accidentally inserted into a slot that is displaced left and right, the tip of the disc 19 comes into contact with the bellows mountain fold portion 5 of the bellows bottom surface 4 and cannot be inserted all the way in. There is also an effect that it is immediately known that the position is wrong. In addition, as a method of not inserting the disc in the displaced position, the bellows side wall 3
There is also a method of coloring the inner surface side of the. That is, the inner surfaces of the left and right side walls 3 of each slot have the same color, and the adjacent slots have different colors. Generally, in a recording disc, data is written from the inner peripheral portion, but in the storage device of the present invention, the portion that holds the disc is the outer peripheral portion of the disc. Furthermore, when inserting or removing the disc, the slot is V
Since it is opened in a letter shape, the contact portion of the disc is substantially the edge portion of the outer periphery of the disc, and there is little fear of damaging the disc surface.

FIG. 3 shows a state in which the spread case 1 of the storage device of this embodiment is closed, and the bellows body is neatly folded and stored in the case. In this state, the contained discs are held in a state of being sandwiched between the folded backs of the bellows, and a large number of discs can be reliably separated and can be stored without taking up space. . In the storage device shown in this example, both end surfaces of the bellows body are spread case 1
Since it is covered by the above, only the upper part, which is the open side surface 7 of the bellows, is exposed to the outside of the storage space. Therefore, in order to prevent dust from entering the storage portion formed by the bellows, it is only necessary to shield the open side surface 7 of the bellows upper portion. In the spread case 1 of this example, the over cover 8 formed at the end of the case is configured to cover the open side surface 7 when the case is closed, so that dust can be prevented from entering. It is desirable that the spread case 1 can be held in a closed state. In this example, a detachable engaging member 9 is attached to the tip of the over cover 8 and a predetermined position of the case.

FIG. 4 is a developed view of the bellows body of the storage device of the present invention. The bellows body has lateral folding lines A and B formed at equal intervals at right angles to the longitudinal direction of the belt-shaped sheet material 6. Two lines are provided at a position where the vertical fold line C bent in an obtuse zigzag at intersections D1 and D2 with the horizontal fold line in a direction substantially perpendicular to the horizontal fold line is line-symmetric with respect to a center line E parallel to the longitudinal direction of the sheet material. It is formed. The zigzag polygonal line F, which shares the outside bending point D2 of the zigzag polygonal line C as an outside bending point, is formed inside the zigzag polygonal line C in two lines at a position symmetrical with respect to the center line E.

The sheet material 6 in which the polygonal lines are formed in this way
By bending so that the dotted line portion is a mountain fold and the solid line portion is a valley fold, a bellows body in which the bellows bottom surface 4 and the bellows side wall surface 3 are integrated is formed. The angle between the bottom surface 4 and the side wall surfaces 3 of the bellows body can be adjusted according to the angle of the zigzag polygonal lines C, F, etc., but particularly in the bellows body of the present invention, the angle between the bottom surface 4 and the side wall surfaces 3 is close to a right angle. Further, it is desirable that the interval between the facing valley portions of the both side walls 3 is formed to be equal to or slightly wider than the width of a predetermined container such as a disk or a card. The bellows body formed by the bending line shown in this figure is
By appropriately selecting the angle of the zigzag polygonal line, it is possible to maintain the angle between the bottom surface 4 and the side wall 3 at a substantially right angle regardless of the expansion / contraction state of the bellows. In the present invention, the angle of these zigzag polygonal lines, the number of lateral polygonal lines, the width, etc. are not defined in detail.

The sheet material 6 used for the bellows body may be paper, cloth, film or the like, and is particularly preferably a material which is not easily broken when bent and which does not damage the disk or card. Further, the sheet materials may have different textures on the front and back sides, and in particular, it is possible to make the bellows inner surface, which is the storage portion, have a soft touch property, or to make the bellows outer surface a waterproof surface.

FIG. 5 shows an example in which a double-spread case 1 itself is formed with a recessed portion so that the bellows body is completely accommodated in the recessed portion when the case is closed. The line fasteners 10 are provided on the outer peripheral edge portions on both sides of the case, and by sealing the line fasteners 10, the entire storage portion can be sealed. The storage device formed in this way is a bag-shaped case particularly suitable for carrying.

In the example shown in FIG. 6, a protrusion 11 is provided on the inner surface of the spread case 1. The projection 11 serves as a contact surface between the cases when the cases are closed, and maintains a constant gap between the front and back surfaces of the cases. When the case is closed,
It is desirable that the front surface and the back surface of the case are substantially parallel to each other, and the bellows body is also maintained in a uniformly reduced state. By providing the main projection 11, even if a strong load is applied to the case surface, the main projection 11 and the spine cover portion 12 of the case receive a force, so that it is possible to prevent stress from being applied to the contents.
Further, as shown in the example of this figure, since the projection 11 is formed at a position that covers the bellows opening side surface 7 in the case where the case is closed, it can also have the function of a dustproof cover.

FIG. 7 shows an example in which the main storage device is attached to the wallet. Recently, credit cards, telephone cards and the like have been widely used, and a card suitable for storing them has been desired. However, the storage device of the present invention can be effectively used for storing these cards. That is, when the front cover 13 is opened, the stored cards 20 are separated at equal intervals, the types of the cards 20 are easily visible, and the spaces between the cards make it easy to insert and remove the cards with a finger. When the front cover 13 is closed, the cards 20 are also in a stacked state, and the storage efficiency is high. In this example, the storage device is integrated with the wallet, but the storage device can be attached to various other bags.

In FIG. 8, one end surface of the bellows body is attached to the bottom surface of a box-shaped case 14 formed in a box shape, and the other end surface of the bellows body is attached to a lid-type case 15 serving as a lid of the box-shaped case 14. The bookcase-type case 14 and the lid-type case 15 are connected only by a bellows body. In the case body of this example, the four side wall surfaces 18 of the box-shaped case 14 are contact surfaces, and both end surfaces of the bellows are parallel to each other when the case is closed. In this example, since the bellows body is housed in the box-shaped case 14 in the folded state, it is easy to improve the airtightness. In this figure, the case is open, and the bellows body is stretched straight in parallel. Regarding the depth of the box-shaped case, it is desirable that the case can be sealed by the lid-type case 15 in a state where the contents are inserted into all the slots of the bellows body.

FIG. 9 shows an example in which an engaging portion 9 is provided on the outer side surface of the spread case 1 so that both outer side surfaces of the case can be attached to and detached from each other. The spine cover portion 12 of the spread case 1 of this example is formed on the same side surface as the bellows side wall surface 3. FIG. 10 shows that the storage device of this example is opened about 360 degrees around the spine cover portion 12 and the outer surfaces of the cases are attached to each other. The bellows-shaped storage portion has a cylindrical storage slot formed in a radial shape, and has high visibility and easy removal. Further, in this state, since the main storage device can stand on its own, the disc can be taken out and put in with the main storage device left. In the present example, the spread case is taken as an example, but even if the case is a split case, by making the outer surfaces of the case bodies capable of engaging with each other,
It is possible to develop the bellows body in a similar form and become independent.

FIG. 11 is an example showing a storage plate 16 having a shape capable of being stored in a slot portion formed by a bellows body. The storage plate 16 is formed with a recessed portion 17 having a predetermined shape, and the recessed portion 17 can accommodate a predetermined shape such as a small recording medium. It is desirable that the thickness of the storage plate 16 does not change even when the contents are set. By using the storage plate as in this example, it becomes possible to store, for example, an ultra-small recording medium used in a digital camera or the like together with a compact disc or the like.

FIG. 12 shows an example in which the elastic body 21 always applies a force in the direction in which the case opens. When the upper lid of the case is closed against the elastic force, the stopper piece 22 projects into the lock hole 23 and engages with it. The lock is released by the operation of the release button 24, and the case is opened by the elastic force. . In this example, the case can be easily opened and closed and the disc can be taken out easily with one hand, so that the disc holder can be comfortably used as a vehicle-mounted disc holder.

[0021]

In the storage device according to the present invention, when the case is opened, the bellows are stretched evenly, and the contents such as the disks 19 sandwiched by the valleys of the bellows are spread at equal intervals, so that the visibility of the label portion is improved. Is improved, and it becomes easier to insert a finger when inserting or removing a disc or the like. In addition, since the valleys of the bellows, which is a slot for storing the discs individually, expands, it is easier to insert the discs into the same part. There is no risk of scratches on the recording surface, as it is only on the edges. In the storage device of the present invention, since the bellows body itself constitutes both side walls 3 and the bottom side 4 of the storage space, the structure is not only simple, but there is no risk of dust entering from the bottom corners. Since the bellows type storage device of the present invention can be configured so that the angle between the side walls and the bottom side is always substantially right regardless of the state of expansion and contraction of the bellows, it has a simple structure and can accommodate a large number of stored items. It becomes possible to store them in an orderly manner.
